The snap-to-trail feature utilizes OpenStreetMap data. Use OSM-based sources like Gaia Topo, OpenHikingMap HD, OpenLandscapeMap HD, and OpenCycleMap HD for best results. You can tap the layers icon to change the map source during route creation:

4. Drag the first point that appears on the map to your desired starting point.

5. Long tap a location on the map to create another point. Plot points and manipulate the line until you have your desired route.

6. Tap the edit icon to delete a point, or create a waypoint.

7. While using a snap-to-trail mode, your route will snap to existing trail data

An elevation profile will appear at the bottom of the screen. Tap and slide your finger across the profile to see the corresponding location along your route.

8. When you finish plotting the route, tap Save at the top-right of the screen. Your route will now be available in your Saved Route list.
